Abstract
A charging method includes: determining, by a control plane function entity (CP), that a data flow that is transmitted by user equipment (UE) on a first data session needs to be migrated to a second data session; charging, by the CP, the data flow on the first UP through a first charging session between the CP and a charging system; obtaining, by the CP, charging information of the data flow before the migration that is counted by the first UP; and determining, by the CP, a quota that is used for the data flow after the migration is necessary to be delivered to the second UP, and delivering the quota to the second UP, thereby charging a service data flow of a user in a case of migration between user planes.
Claims23
A method, comprising:
- determining, by a control plane function entity, that a data flow being transmitted by user equipment (UE) on a first data session needs to be migrated to a second data session, wherein the first data session is between the UE and a first user plane function entity, the second data session is between the UE and a second user plane function entity, and the first user plane function entity and the second user plane function entity correspond to the control plane function entity and separately connect to the control plane function entity;
- obtaining, by the control plane function entity, charging information of a first quota before the migration, wherein the first quota was requested by the control plane function entity from a charging system, the charging information of the first quota before the migration is counted by the first user plane function entity, and the charging information comprises usage information;
- determining, by the control plane function entity based on the first quota and the charging information of the first quota, a second quota for the data flow after the migration, wherein the second quota is based on a remaining available quota of the first quota;
- and
- delivering, by the control plane function entity, the second quota to the second user plane function entity.
